Lumbar stenosis surgery: Spine surgeons not insurance companies should decide when enough is better than too much

Background Lumbar surgery for spinal stenosis is the most common spine operation being performed in older patients. Nevertheless, every time we want to schedule surgery, we confront the insurance industry. More often than not they demand patients first undergo epidural steroid injections (ESI); clearly they are not aware of ESI's lack of long-term efficacy. Who put these insurance companies in charge anyway? We did. How? Through performing too many unnecessary or overly extensive spinal operations (e.g., interbody fusions and instrumented fusions) without sufficient clinical and/or radiographic indications. Methods Patients with lumbar spinal stenosis with/without degenerative spondylolisthesis (DS) are being offered decompressions alone and/or unnecessarily extensive interbody and/or instrumented fusions. Furthermore, a cursory review of the literature largely demonstrates comparable outcomes for decompressions alone vs. decompressions/in situ fusions vs. interbody/instrumented fusions. Results Too many older patients are being subjected to unnecessary lumbar spine surgery, some with additional interbody/non instrumented or instrumented fusions, without adequate clinical/neurodiagnostic indications. Conclusions The decision to perform spine surgery for lumbar stenosis/DS, including decompression alone, decompression with non instrumented or instrumented fusion should be in the hands of competent spinal surgeons with their patients' best outcomes in mind. Presently, insurance companies have stepped into the "void" left by spinal surgeons' failing to regulate when, what type, and why spinal surgery is being offered to patients with spinal stenosis. Clearly, spine surgeons need to establish guidelines to maximize patient safety and outcomes for lumbar stenosis surgery. We need to remove insurance companies from their present roles as the "spinal police."
